Self-esteem predicts quality of responding to interview questions when skill in responding is low

► We examine interactions between skill in responding and self-esteem in interviews. ► We indexed skill as effectiveness in resisting unanswerable questions. ► Esteem positively predicted accuracy for answerable questions when skill was low. ► When skill was low individuals overestimated their ability. ► High trait esteem prevented awareness of low skill. Self-esteem, skill in responding, and skill appraisals have each been posited to influence the quality of information gathered during interviews about witnessed events. This study examined whether self-esteem exacerbates or buffers skill related deficits and awareness of skill. Participants viewed a video, completed measures of self-esteem, estimated their skill in responding, responded to answerable and unanswerable questions about the video, and re-estimated their skill. Skill was indexed as effectiveness in resisting unanswerable questions. Moderated regression analyses showed that high self-esteem was associated with higher accuracy and fewer errors to answerable questions, but only when skill was low. Low skill individuals overestimated their ability. Following practice, low skill individuals with low trait self-esteem recalibrated their skill appraisals, while low skill high self-esteem individuals did not become aware of their lack of skill. When skill was high, self-esteem was not related to responding. Understanding the influence of self-esteem on the quality of information gathered during interviews about witnessed events requires attention to interactions with skill and performance appraisals.
